A method and apparatus are provided for recovering an amine solvent from an acid gas stream. The apparatus includes a water wash recovery column, a nozzle for spraying water wash and an amine nucleation agent into the water wash recovery column and an inlet port for introducing acid gas into the water wash recovery column adjacent the lower end thereof. The method includes the steps of treating the acid gas stream in the water wash recovery column with a counter-current flow of water wash in an amine nucleation agent, discharging treated acid gas from an upper end of the water wash recovery column and collecting water wash, amine nucleation agent and entrained amine solvent from the acid gas stream and a sump at a lower end of the water wash recovery column.

Apparatus and method for recovering an amine solvent from an acid gas stream

A method of removing and capturing an acid gas from a fluid stream includes exposing the fluid stream to an aqueous scrubbing solution in the presence of a packing element including alternating hydrophobic and hydrophilic features or zones. A related apparatus is also disclosed.

Method and apparatus for increasing mass transfer in aqueous gas adsorption processes

The present invention relates to methods for improving carbon capture by providing particles within an amine solvent. The particles provide for increased turbulence at the interface between the counter-flowing gas and solvent, which allows for increased amine and carbamate salt diffusion between the liquid film and bulk.

COmass transfer enhancement of aqueous amine solvents by particle additives

The present invention relates to methods for improving carbon capture using entrained catalytic-particles within an amine solvent. The particles are functionalized and appended with a COhydration catalyst to enhance the kinetics of COhydration and improve overall mass transfer of COfrom an acid gas.
